CCNA Data Center on vBrownBag

Sometimes when I’m writing blog posts, I forget how important it is to start off on the right foot. For a lot of networking people just starting out, discussions about advanced SDN topics and new theories can seem overwhelming when you’re trying to figure out things like subnetting or even what a switch really is. While I don’t write about entry level topics often, I had the good fortune recently to talk about them on the vBrownBag podcast.

For those that may not be familiar, vBrownBag is a great series that goes into depth about a number of technology topics. Historically, vBrownBag has been focused on virtualization topics. Now, with the advent of virtual networking become more integrated into virtualization the vBrownBag organizers asked me if I’d be willing to jump on and talk about the CCNA Data Center. Of course I took the opportunity to lend my voice to what will hopefully be the start of some promising data center networking careers.

These are the two videos I recorded. The vBrownBag is usually a one-hour show. I somehow managed to go an hour and half on both. I realized there is just so much knowledge that goes into these certifications that I couldn’t do it all even if I had six hours.

Also, in the midst of my preparation, I found a few resources that I wanted to share with the community for them to get the most out of the experience.

Todd Lamle’s NX-OS Simulator – If you can’t get rack time on a real Nexus, this is pretty close to the real thing. You should check it out even if only to get familiar with the NX-OS CLI.

NX-OS and Nexus Switching, 2nd Edition – This is more for post-grad work. Ron Fuller (@CCIE5851) helped write the definitive guide to NX-OS. If you are going to work on Nexus gear, you need a copy of this handy. Be sure to use the code “NETNERD” to get it for 30% off!

Tom’s Take

Never forget where you started. The advanced topics we discuss take a lot for granted in the basic knowledge department. Always be sure to give a little back to the community in that regard. The network engineer you help shepherd today may end up being the one that saves your job in the future. Take the time to show people the ropes. Otherwise you’ll end up hanging yourself.
